Lift is the force that directly opposes the weight of an
airplane and holds the airplane in the air. Lift is generated by every part of
the airplane, but most of the lift on a normal airliner is generated by the
wings. Lift is a mechanical aerodynamic force produced by the motion of the
airplane through the air. Because lift is a force, it is a vector quantity,
having both a magnitude and a direction associated with it. Lift acts through
the center of pressure of the object and is directed perpendicular to the flow direction.
There are several factors which affect the magnitude of lift. Continue...
